Tk,
I don't know if the brother standing up for you hurt you or not. I would, however, be proud of the fact that someone is noticing your changes.

In regards to the MIL, ignore her. If she continues pull her aside and let her know that while you respect her you will not allow her to be disrespectful towards you. You can even tell her how surprised you are at her behaviour as she experienced the pain you are feeling now. Just my two cents.
